If neither of these two things are a concern for you, you should be fine:
Pregnant Women
According to the MayoClinic, since saw palmetto has a distinct effect on the endocrine system (the hormones) in the body, it is best to avoid the herbal remedy when pregnant or breastfeeding. Also, some tinctures of saw palmetto contain high concentrations of alcohol, which should not be ingested during pregnancy as well. Saw palmetto is thought to reduce the conversion of testosterone into dihydrotestosterone, which may end up upsetting the balance between estrogen and testosterone. This hormone balance is extremely important during pregnancy and should not be altered.
Women on Birth Control
For the same reasons, women who are using birth control should first consult their doctor or naturopath before taking saw palmetto. Birth control works on the mechanism of altering female hormones to regulate the menstrual cycle. If taking saw palmetto, the level of hormones that you are supposed at a certain point in your cycle may change, this might cause your birth control to be less effective. Also, the MayoClinic points out that saw palmetto has in some cases been associated with increased risk of bleeding, which might end up making menstrual periods heavier and more difficult.
